REFRIGERATOR.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed April 13, 1916. Serial N 0. 90,897.

To all whom it may concern:

Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to refrigerators and particularly to a removable drain pipe and chamber therefor, and the primary objects of the invention are to provide a refrigerator with a supplemental drain pipe chamber having an exteriorly accessible closure which may be opened to conveniently remove the drain pipe without exposing the main interior'portion' of the refrigerator, and also to locate a drain pipe within a part of a refrigerator in such manner that it may be easily reached and removed for cleaning and afterward readily replaced in operative position.

A very serious defect in refrigerators from a sanitary standpoint is that the drain pipes thereof become obstructed and the water overflows into the provision chamber, and when this water is contaminated with the deposit from manufactured ice, for instance, it is very'objcctionable. To thoroughly clean a provision chamber in which the drain water has overfiowed it is necessary to remove all the provisions therefrom and take out the shelves before the drain pipe under ordinary arrangements can be removed. This requires considerable time, and, furthermore, in a great many cases'the 'edibles and other articles within the provision chamber are rendered unfit for consumption when contaminated by the drain water from manufactured ice, the drain water from the latter kind of ice having a very objectionable scum or deposit which is not at all sanitary for many reasons.

The improved drain pipe arrangement can be used in practically all makes of refrigerators with a few minor changes at very little additional expense, and a refrigerator equipped with this improved drain pipe ar rangement is absolutely sanitary, as the pipe may be easily and readily cleaned without disturbing the provision chamber or ice chamber or the contents of the latter in any manner whatsoever. I The improved drain pipe arrangement is very simple in its organization and the additional expense incident to thechange necessary to install the tages accruing therefrom.-

In the drawing:

Figure 1 isafront elevation of a refrigerator showing the improved drain pipe arrangement installed therein and the chamber for the drain pipe illustrated as open.

Fig. 2 is a transverse vertical section taken in the plane of the line 22, Fig. 1, and showing the drain pipe chamber closed.

Fig. 3 is a horizontal section taken in the plane of the line 33, Fig. 2.

Fig. 4 is a detail elevation of a part of the refrigerator showing a slight modification.

The numeral 5 designates a refrigerator which may be of any preferred construction ,and provided with 'an upper ice chamber 6 and a lower provision or storage chamber 7. The ice cliamberhas a lower drip or drain pan 8 which is shown with an oil'-v set or extension 9 at one corner, see Fig. 3, projecting into a supplemental chamber 10 which has an exterior closure 11 which may be secured in place when closed by any suitable means, but is preferably a slip panel that may drop into a slot at the bottom and secured .at the top by .a fastening 12 which may be of any form. In some instances the panel may be hinged at the side as shown by Fig. 4. The supplemental chamber 10 may be located in other positions. or in different parts of the refrigerator, as may be desired. The extension 9 of the drip pan or drain 8 has a short depending outlet nipple 13, and thereunder in the chamber 10 a drain pipe 11 is vertically disposed and held by any suitable means, such as clips 15, as illustrated by Figs. 1 and 2, or by any other device'or devices adapted for the purpose. The .drain pipe 14 is removable from the chamber 10 through the front outlet opening 15 of said chamber which is normally covered by the door or panel 11. The supplemental chamber 10 is in the form of a recess constructed in the front wall of the refrigerator, but it may be otherwise located. This chamber or recess is lined atthe back and on the two sides with any light metal, such as galvanized iron .or zinc, as

r I same is immaterial compared to the advan- Beit known that I, ALFoxso H. DUNLAPL a citizen of the United States, residing at at 16 and 17, to protect the refrigerator walls from any dampness. It is also proposed to construct the drain pipe in any manner desired and to equip the same with a' trapat the bottom as usual if desired.

Should the drain pipe become. clogged or obstructed from any cause the drain water would run through the supplemental chamber to the floor of the latter and out through the opening at the bottom of the supplemental chamber 10 and could not unout liability of contamination of t of the provision chamber 7 and, moreover,

der any conditions flow into the provision chamber.

From the foregoing it will be seen that the drain water from the ice chamber is carried off through the drain pipe 14 with- 18 contents when the drain pipe becomes obstructed or clogged with sediment it may be easily removed and cleaned and afterward replaced.

' This ready removal of the drain pipe at any time is made possible by the provision of the supplemental chamber or recess 10 which ,is exteriorly accessible.

It will be understood that the proportions and general dimenslons of the chamber or recess 10 and the drip pipe 1i may be varied to adapt the same to different applications or installment in refrigerators of different" sizes.

\Vhat is claimed is: 1. A refrigerator having a chamber supplemental to the usual refrigerating chambers and exteriorly accessible, a removable closure for the said supplemental chamber, and a drain pipe removably mounted in the said supplemental chamber and having the lower end thereof in separable outlet cooperation with the bottom of the refrigerator, the supplemental chamber and closure therefor being of such length and width that the drain pipe practically as a whole is exposed for removal when the said closure isopened.

2. A refrigerator having the usual ice and storage chambers and an additional drain ing into the additional chamber, and a drain pipe mounted in the additional chamber and removable and replaceable through the exterior opening of said additional chamber and in separable outlet cooperation'with the 3. A refrigerator having an opening through a portion of the wall thereof in addition to the usual refrigerator openings, an exteriorly located closure for the said opening, and a drain pipe mounted in rear of, the said closure and having the lower extremity thereof extending through the bottom of the refrigerator and removable and replaceable through the said opening Which is normally closed by the said closure, said opening extending vertically at one side of the main refrigerator door and when cleared exposing practically the entire drain pipe which may be removed and reset as a whole relatively to the refrigerator.

4. A refrigerator having the usual ice and provision chambers and a supplemental drain pipe receiving chamber which is exposable from the exterior of the refrigerator and separated from the remaining refrigerator chambers, a drain pipe shiftable in and removable from said supplemental chamber, the supplemental chamber being .of a length to expose the greater portion of and permit the drain pipe as a whole to be removed therefrom through'the outerfside portion of the'refrigerator and also to be replaced as anentirety in the said supplemental chamber, and means for engaging and holding the drain pipe in normal position within the supplemental chamber.
